' the pane or corresponding parts panes l of glass or a similar transparentd and a transparent retaining' vhlm or Be it known that I, OTTO Gonrznn, a citizen of the United States, residing at Jersey City, in the county of `Hudson and State of New Jersey, have invented new and useful Improvements in Transparent Panes, of which the following is a specification.

rlhis invention relates to a transparent pane comp-rising a plate of glass which is provided with means whereby the glass when broken or cracked will not be dismembered to anyconsiderable' extent but remain practically intact and continue to serve as a pane notwithstanding that the same has been injured.

Heretofore this has usually been accomplished by embedding in the pane a glass wire fabric which holds together' the several parts of the pane in case the same is broken or cracked. This, however, is objectionable on account of the difficulty of embodying a woveny wire fabric in the glass and also the unsightliness of this fabric especially when used in high grade or finished work.

it is the object of this invention to reinforce or strengthen a pane having one or more plates of glass by means which are practically indestructible and hold practiv cally all of parts of'a broken plate of glass-in place but which are fully transparent so as not to obstruct the view through detract from its appearance, and to accomplish this'purpose in an economical and comparatively inexpensive manner. v

lin the accompanying drawings: Figures l, 2, 3 and a are vertical sections of dierent embodiments of my invention., Fig. 5 is a side elevation of a framed window constructed in accordance with one form of my improvements.

Similar characters of reference indicate throughout the several views. v

'fn lthe simplest form shown in Fig. l, the same comprises two fragile material,

sheet 2 of a suitable tough adhesive and resilient cement or similar material such as glucose arranged between the plates of i glass so as to adhere iirmly thereto and form practically'an integral part thereof. This retaining iilm; may be applied to,` the oppos- `,the edges of the glass parent of my invention, as

'unit yand prevent the ing sides of the plates of glass while in a freely liquid] state and then allowing the same to dry to a viscous condition. This retaining film does not interfere with the transparency of the pane as a whole but if the latter should be struck or injured by any object the retaining film operates to cushion the blow against the pane so as to reduce the fracture and it also serves to hold the several pieces of glass .together so that they do not become disconnected,thereby preserving the pane practically intact so that its function as a closure or window is maintained notwithstanding that the glass portion of the pane has been injured.

if desired the pouring of a liquid retaining hlm 3 between two plates il, i of glass may be facilitated and an increase obtained in the firmness or strength of the connection. between the marginal parts of the film and these plates by beveling the inner corners or plates so that t e bevels of the'opposing plates converge inwardly, as shown at 5 in Fig. 2. r`lhis inwardly converging space formed between the edges of the glass plates permits .of readily -pouring the liquid film between the plates and also produces an enlargement or bead 6 on the marginal parts which materially cushions this pane at its edges and enables the 'saine to withstand greatereshocls when mounted in a framewithout liability of `disinteg-ration of the glass plates or impairing the general efficiency of the pane. i

instead of depending solely upon the trans glass togetherin plates are cracked or plate 7 of non-fragile such as celluloid or mica may be arranged broken a supporting between two glass plates 8, 8 and transparent iilms 9, 9, of cement of the character described may be interposed between opposite sides of the supporting plateand tie glass plates, as shown in Fig. 3. rilhis cement opcrates to securely connect the non-fra ule supporting plates and the glass plates, so t Lat these various elements form practically broken, from flying apart. e

A further modication or this vconstruction is snownxin Fig. l in which two transs parentsupporting plates i0, l0 of `anp7 suitableynonfjragile material such as celluloid of the film' lm for holding the fragments ofthe event that the glass transparent 'material glass, if crackedIv or i or mica are arranged side by side between two glass plates 11, 11 and a central transparent film 12 of cement is arranged between the opposing sides of the two supporting plates, and two transparent films 13, 13 of cement are arranged between'the trans parent supporting plates and the glass. plates, the several members being connected' adhesively withfeach other so as to practically form an integral mass which constitutes a pane and may be used for windows or for other purposes.

When the transparent cement in the construction shown in Figs. 3 and 4: has become dry or viscousor substantially so the celluloid or mica supporting plate and these films between the glass plates form a very strong, tough resilient and durable connection between the glass plates which operates effectively to hold the several pieces of glass together in the event that the same become broken and fractured and these celluloid or mica plates together with the films of cement also form a cushion which operates to check the force of a blow delivered against the pane and reduce the extent of the fracture of the glass to a minimum. By this means the pane will be maintained in its entirety or unperforated condition notwithstanding that the same is cracked or broken and thereby enables the pane to continue in service until the same can be replaced by a new one.

If desired this pane may be constructed in any suitable shape or contour, Fig. 5 being one example of the various forms in which the same may be made and as there shown the pane has the form of an oblong rectangle.

The paneV may also be mounted in any suitablemanner either in a frame or secured in the opening intended to receive the same. In case the pane is mounted in a frame the latter may be so constructed that its several members are of rectangular channel-shape in cross section, as shown at 14 in Fig. 3, and the edges of the pane may be arranged in the concaved sides ofv these frame members, as shown in this ligure, and secured therein in any suitable manner, for instance by the cement which connects the glass and celluloid plates, as shown `at 15. Any vother suitable cross sectional form of frame may, however, be employed, if le-v sired,for instance, as shown in Fig. 4, the frame 16 has its members constructed in the form of a round tube 011e side of which is .l slotted to permit of inserting the edge of the pane within the tubular frame member andsecuring the same therein by the cement 17 which connects the plates 10, 11, or by any other suitable means.

In the event that the pane is of oblong form the frame may be of corresponding forms, as shown in Fig. 5.

`In all of the various forms of my invention which are shown in the drawings and described in the foregoing part of the specification the reinforcement of the glass portion thereof is effected by means which are not only transparentso as not to detract from the appearance of the window in which the same may be mounted, but the same also operates to cushion Or deaden the blow which may be delivered against the pane and thus minimize the fracture and prolong the usefulness of the pane wherever the same is installed.

I claim as my invention:

1. A transparent pane comprising two or more glass plates having beveled edges converging inwardly, a sheet of celluloid .between said glass plates coated on both sides thereof with transparent glucose,and means for retaining a triangular body of soft glucose within said beveled edges and joining the beveled edges of said glass plates together.

2. A transparent pane comprising a plurality of glass plates having beveled edges yconverging inwardly, a sheet `of celluloid between said plates coated on both sides thereof with softtransparent glucose,'and means for retaining and inclosing a shock absorbing cushion of soft glucose in the beveled end spaces of said plates.

3. A transparent pane comprising two glass plates having beveled edges converging inwardly, a celluloid plate arranged between said glassplates, and a soft transparent cushion of glucose cement, filling the'.

beveled spaces at the edges'of said plates, thence running on and connecting the opposite sides vof said celluloid plate with said glass plates and means at the edges of said glass plates for permanently inclosing the said glucose cushions. 4. A transparent pane including, in combination, two glass lates coated on their interior opposite sur aces with transparent glucose, a celluloid plate between said glass plates, cushioning means between the edges of said glass plates and means holdingthe edges together.
